Abstract

PURPOSE:To prevent occurrence of printing marks in operation of a printer which prints single pieces of paper in a condition in which a continuous form is set by rotating the platen for a fixed quantity of the continuous form also. CONSTITUTION:When the single piece of a slip 6 is detected by a sensor 26, a control unit 8 changes a switch 14 to Y side and a frequency divider 13 is set at a frequency dividing ratio, for instance, of such as to carry 1/120inch of a continuous form 5 at each time for a new line of the single piece of the slip 6, and the single piece of the slip 6 is carried for 1/6inch in the (b) direction and the continuous form 5 is carried for 1/20inch in the (c) direction by a motor 2 respectively for each new line. And when printing of the single piece of the slip is over, the single piece of the slip 6 is carried in the reverse of (b) direction and at the time when the tail of the piece is detected by the sensor 26, the switch 14 is changed over to X side and the control unit 8 sets a motor control section 9 at a value of a counter 15 and the rotation of a motor 1 is reversed to return the continuous form 5 to the original position. Thus, an occurrence of printing marks on a continuous form is prevented and a waste of paper is eliminated.

Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a printer control system, particularly a continuous printer control system.

This invention relates to a printer control system for a printer that handles paper and slips.

[Background of the invention]

゛Impact type printer that handles continuous paper and single sheets.

As a link, for example, Japanese Patent Publication No. 56-25586.

The technology shown in this report is known. In other words, when printing on 10 consecutive sheets of paper, print these sheets one after another.

Printing is carried out while feeding, and when printing on a cut sheet, K is used to feed and print on such paper one after another while the continuous paper is set on the platen.

In this case, when printing on a cut sheet, the continuous paper remains stopped on the platen 5, and the cut sheet is printed by another feeding means with line feeds in order. However, if the printing medium in the form of a single sheet is particularly thick like a passbook, there is no problem, but for single or two to three sheet-like sheets, the print head cannot print continuously through this single sheet. It makes an impact on the same place on the paper, so it is suitable for continuous paper.
Traces of printing occur. In addition, since impact is applied to the same portion of the platen, its wear and tear is also increased.

[Purpose of the invention]

The object of the present invention is to eliminate the above-mentioned drawbacks.

Continuous paper is set on the platen and turned into single sheets.

Continuously when printing single sheets on printers that print.

A printer control system that prevents printing marks on specific parts of the paper and prevents wear and tear on the printer 3, 1 Latin as much as possible.

Our goal is to provide the following.

[Summary of the invention]

The present invention can be applied to continuous paper and plastic when printing single sheets.

The printing operation is performed at the same location on the tenth scale.

In order to prevent this, the platen is rotated by a predetermined amount every time one line of the ticket is printed, thereby feeding the continuous paper by a predetermined amount. Here, the predetermined amount may be an amount corresponding to one line of a ticket, or may be an amount even more or less than the negative amount. In addition, in order to eliminate wasted paper that occurs when continuous paper is fed, the continuous paper is controlled so that it is returned to its original position at the end of single-sheet printing.

[Embodiments of the invention] 5 An embodiment of the present invention will be described below with reference to one drawing.

I will explain.

FIG. 1 is a diagram showing a schematic configuration of a printer.

be.

This printer is a so-called wire matrix printer.

It is a real printer. Multiple wires are confused.

A known print head 3 is arranged in a matrix.

driven by known drive means (not shown).

Movement is controlled in the direction of arrow α. Go to print 5.

A platen 4 is placed oppositely and parallel to the arrow α direction.

placed. This platen 4 is a so-called cylindrical platen, and when the motor 1 is driven to rotate in the forward and reverse directions, the platen 4 is rotated in the directions of arrows C and e (
(Fig. 2). Therefore, the continuous paper 5 set on this platen 4 is fed in the direction of arrow C and the direction of arrow 6. -Printing on the continuous paper 15 is performed in this state.

A cut sheet 6 is further guided and fed onto the continuous paper 5 set on the platen 4. That is, by selectively driving the wires of the printing head 5, the ink ribbon 7
Information will be printed on the cut sheet 6 via the.

Here, the cut sheet 6 is used as a feeding means for the continuous paper 5.

is determined by another means in the direction of the arrow and in the d direction (the direction of the arrow).

Figure 2). That is, with the print head 511+ as the boundary, the feeding rollers 24. .

25 are provided. Motor 2 has forward and reverse directions.

When it is rotationally driven, it becomes low via the belts 22 and 25.

24 and 25 are rotated, and the cut sheet is rotated in the direction of arrow A and d.

feed in the direction. 15 In this way, continuous paper 51 single sheet 6 has motor 1% motor 2
It is understood that each feed is controlled independently by the following.

These motors 1 and 2 are characteristically controlled by this embodiment.

・4・ The control block is shown in FIG. In this figure, motor 1 and motor 2 are both ball motors. These motors 1 and 2 each have a motor driver 1
1.12, it is rotationally driven in the forward and reverse directions. The amount and direction of rotation of the motors 1 and 2 are controlled by motor control units 9 and 10. The amounts and directions of these rotations are shown.

data after this printer is powered on.

It is sent from the control device 8 to each control section 9,10.

In this example, motor 1. is a pulse motor. .

2: 1 A20 inch paper per 1 pulse.

It is set in advance to feed. For example, Ren.

1/6 (=20 x 1/12o) of continuation sheet 5 and cut sheet 6.

Rotation amount if you want to break lines independently for each inch.

Data indicating 20 pulses is set in the control unit 8 and the five remote control units 9 and 10. Of course, the J motors 1 and 2 are driven to rotate independently depending on the amount of rotation.

In particular, a divider 13 is provided to divide the rotation amount, which is the output of the motor control section 10. The frequency division ratio of this frequency divider 15 may be any value and is set by the control device 8. In this example, 5 continuous sheets are fed by a predetermined amount at the time of line break of the single sheet 6. For example, 1. Line feed 6 by 1/6 inch, and at the same time, repeat.

When the next sheet 5 is to be line-feeded by 1A20 inches, - is set by the control device 8 as the dividing layer ratio.

It becomes 0. The output of the branch divider 15 is sent to the counter 15° and the terminal Y of the switch 14. counter.

15 is a cumulative value obtained by counting the output of the frequency divider 15.

hold. 2. .

Therefore, as will be understood from the explanation below, this.

The cumulative value of the counter 15 is the number of times the motor 1 operates when the continuous sheet 5° is finally line-broken together with the single sheet 6.

It shows the amount of transfer.

The switch 14 functions as a switching means for switching between feeding the continuous paper 5 alone or feeding it together with the single sheet 6. This switching is performed by a control signal from the control device 8. 1. That is, the control device 8 monitors the output signal of the sensor 26 in order to detect whether or not the cut sheet 6 has been discharged.
When the presence/absence of a cut sheet is detected, it is assumed that the cut sheet 6 is fed on top of the continuous paper 5, and the switch 14 is set to the Y terminal.

Emit a control signal to connect. On the other hand, if it is detected that the ticket 6 is discharged or absent, the control section connects the switch 14 to the X terminal.

issue a number.

Therefore, when printing on continuous paper 5,

Motor control unit 9 via the X terminal of 14.

The direction of rotation is instructed to the motor driver 11.

At the same time, the amount of rotation is given. For example, mentioned above.

The motor 1 is rotated so as to feed continuous paper 5° in 1/6 inch increments. On the other hand, mark ticket 6.

If you want to use the switch, connect it to the Y terminal of the switch.

- The frequency-divided value from the motor control unit 10 is given to the motor drive 11. For example, as described above, motor 2 is rotated to feed each print medium by 1/6 inch, and motor 1 is rotated to feed each print medium by 20 inches.

In this embodiment, the value of the counter 15 is effectively used. As mentioned above, when printing the cut sheet 6, the continuous paper 5 is also fed at the same time, so if printing is started on the continuous paper 5 from the same state after the cut sheet 6' is ejected, the above-mentioned feed will occur. Continuous paper only.

is wasted. Continuous paper 5 is 51/i as in the above example.
If it is sent in small increments of 2o inches, there is nothing.

The amount wasted is not that big. However, the above.

The branching ratio of the branching unit 130 is set to an arbitrary value by the control device 8.

When set, the feeding amount of single sheet 6 and continuous paper 5.

The feeding amount will be exactly the same, continuous paper in this case.

The waste of 5 becomes obvious.

Thus, the sensor 26 detects the discharge of the ticket 6.

When this happens, the control device 8 sets the switch 14 to the X terminal side.

At the same time, the value of the counter 15 is taken in and the 1,5 motor control unit 9 is controlled to reversely rotate the motor 1 by the value of the counter 15. As a result of this, the motor 1 is rotated in the reverse direction, and the continuous paper 5 is rotated.

The cut sheet 6 is returned to the position corresponding to the printing start position.

Next, the operation of the embodiment will be explained with reference to FIGS. 4 and 2.

When the cut sheet 6 is detected by the sensor 26 shown in FIG.

The 8-digit switch □ 14 is controlled to be switched to the :Y side, but the frequency division ratio is also sent to the frequency divider 15 from the control device □ 8.

It will be displayed. In this example, for example, the single sheet has a single line break.

Each continuous paper 5 is fed 1A20 inches.

The branching ratio 1/2o is set as follows. This state.

Then, printing is performed on the cut sheet, and the cut sheet 6 is shown in the direction of arrow d.

□ Continuous paper 5 is moved in the C direction by 1/61 inch in the direction.

, the line is broken one by one (Figure 2).

When the printing of the cut sheet 6 is completed, the cut sheet 6 is moved to the arrow d.

It is fed to be discharged in the direction. Then part of the sensor 26
When detected, the control device 8 controls the sensor 514 to switch by X1tll. Then, the control device 8 reads the value of the counter 15, and the value of the counter 15 is transferred to the motor control unit 9, and the motor 1 is rotated in the reverse direction.

give a deposit. The motor 1 is then rotated in the reverse direction, and the continuous paper 5 is fed in the direction of arrow e by a distance t shown in FIG. 2(h), and is returned to this state.

As described above, according to this embodiment, printing K on a single sheet.

At this time, the platen 4 is rotated a predetermined amount at a time.

Since the continuous paper 5 is fed, the continuous paper 5 and the platen 4
Inva from the print head at the same location.

Continuous paper 5 & C traces because no ct is given.

occurrence is prevented. After printing the single sheet.

of continuous paper because the continuous paper is returned to its original position.

Waste is also prevented. ,.

Incidentally, in the above embodiment, it is set in the branching unit.

The frequency division ratio is such that continuous paper is fed by 1A 20 inches.

It was set as, but not limited to, 1A8o in.

*'/so inch* Enter any value such as 1/so inch.

can be For example, if the division ratio is 1, -
The feeding amount of the continuous paper 5 is the same as that of the single sheet 6. Therefore, in this case, 1 branch unit 15. It is understood that the switch 14 is not necessary, and it is sufficient to set the same amount of rotation in the motor control units 9 and 10, and to control the motor control unit 9 in the same manner as the motor control unit 10 during ticket printing. Of course, in this case, the force/counter 15 may count and accumulate the values from the motor control section 9 or 10 one after another.

Furthermore, as another modification, the continuous paper 5 is fed backwards.

The control for returning the cut sheet 6 to its original position does not necessarily have to be performed by detecting the ejection of the cut sheet 6 using the sensor 26.

Continuous paper 5 and single sheet 6 are fed independently.

The cut sheet 6 is held between rollers 24 and 25.

So, for example, when printing on the cut sheet 6 is finished.

Then, the control device 8 detects that the data has been outputted, and continues the process without ejecting the ticket 6.

It is also possible to send only the subsequent paper 5 in the reverse direction. Is this so?

The matters to be understood are also easily understood.

Further, the control device 8 predicts the number of lines to be printed on the cut sheet 6.

It is also possible to recognize this and advance the continuous paper 5 by a certain amount before printing on the cut sheet, and then feed the continuous paper 5 by a predetermined amount at the same time as the line feed of the cut sheet 6. good.

Furthermore, it will be easily understood that the present invention is applicable not only to known serial type impact printers but also to known line type impact printers.

Of course, various other modifications can be made.b [Effects of the Invention] As explained above, according to the present invention, single sheet printing is possible.

Since continuous paper is also fed during this process, impact is exerted on the continuous paper, paper, and similar parts of the platen.

There are traces of printing on continuous paper.

This improves the adhesion and reduces wear and tear on the platen.

do not have. I11 Furthermore, after printing a single sheet, the continuous paper is set at this position.

Therefore, waste of continuous paper is prevented. .
